Fusing Satellite Data To Monitor The Urban Area's Effect On Plant Phenology, Norman Gervais
Fusing Satellite Data To Monitor The Urban Area's Effect On Plant Phenology, Norman Gervais
Legacy Theses & Dissertations (2009 - 2024)
This dissertation centrally focuses on developing and validating the use of fused satellite imagery to monitor the effects of the urban area on plant phenology, specifically the timing of the start and end of the growing season (SOS and EOS, respectively). In the first paper, Chapter 2, data from the Moderate Resolution Imaging Spectroradiometer (MODIS) and Landsat were fused together using the Spatial and Temporal Adaptive Reflectance Fusion Model (STARFM) to produce a time series of a high spatial and high temporal resolution vegetation index. From this time series, the SOS and EOS were extracted and compared between the urban …
Visual Variables On Mobile Devices : An Empirical Study Of Their Roles In Gaining Spatial Awareness, Andrew Donghyun Kim
Visual Variables On Mobile Devices : An Empirical Study Of Their Roles In Gaining Spatial Awareness, Andrew Donghyun Kim
Legacy Theses & Dissertations (2009 - 2024)
More people are used to and comfortable using mobile devices compared to traditional paper maps. Multiple studies have suggested that user's spatial awareness tends to decrease as the user passively follows directions on a mobile device with diminished screen size. One way to overcome the shortcoming of the small screen is through displaying discrete off-screen objects (landmarks) located beyond the extent of mobile map displays. The current study empirically examines the effectiveness of using visual variables including size, fuzziness, and transparency to embed distance and direction information in implicit icons of off-screen objects. This study investigates the effectiveness of these …
